According to the inquiry of Magic Health Network, generally speaking, 45 degrees is definitely more fuel efficient, but there is little difference in actual gas consumption between 45 degrees and 60 degrees. It depends on the ambient temperature. If the temperature is too low, there may be no heating effect. How to adjust the temperature depends on the temperature. For example, a 45-degree wall-hung boiler can only guarantee a room temperature of about 20 degrees, and a 50-degree wall-hung boiler can only guarantee a room temperature of about 25 degrees. If there is no floor heating at home and there is no heating upstairs and downstairs, then the room temperature of the 45-degree wall-hung boiler can only reach about 16 degrees. In addition, if there is a thermostat in the room, the gas-fired wall-hung boiler only consumes natural gas in the combustion state. If the room temperature has reached the standard, the gas-fired wall-hung boiler will be closed and will not stop gas. In this case, there is little difference between the gas consumption set to 45 degrees or 50 degrees and 55 degrees, and the room temperature remains unchanged.

Natural gas refers to all natural gas, including gases formed by various natural processes in the atmosphere, hydrosphere and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane and biogas, etc.). ). The commonly used definition of "natural gas" for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the stratum. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is mainly hydrocarbons and contains non-hydrocarbon gases.
